JOSEPH L. POTTER, OF INDIANAPOLIS, INDIANA.

SCRAPING-EXCAVATOR AND CONVEYER.

To all whom it may concern:

Be it known that I, JOSEPH L. Por'rnn, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Scraping-Excavators and Conveyers; and l do declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, and to the letters and iigures of reference marked thereon, which form a part of this specification.

This invention relates to apparatus whereby excavations may be made and the earth from the excavations conveyed and dumped into the excavations after completing the structural work therein as the work proceeds while constructing sewers or the like, the invention having reference particularly to the structure and arrangement for operation of the excavating' implement, and the structure and arrangement of the conveying apparatus, and also the mechanism for their operation.

rlhe object of the invention is to provide simple, compact. and relatively cheap apparatus of the above-mentioned character that will be adapted to be operated expeditiously by the least number of attendants, and particularly when it is desirable to convey the earth a considerable distance back of the point of excavating operations, which apparatus will be reliable, durable and economical in use.

lVith the above-mentioned and other objects in view the invention consists in improved excavating and conveying apparatus comprising a novel scraping and elevating implement, a novel conveying car to receive the earth from the implement and convey it back beyond the place of operations in the excavation, and a novel arrangement of means for operating and controlling the implement and the conveying car.

The invention consists further in the parts and combinations and arrangements of parts as hereinafter particularly described and then defined in the accompanying claims.

Referring to the drawings, Figure 1 is a side elevation of the apparatus partially broken away; Fig. 2, a top plan thereof in which parts are broken away; Fig. 3, a fragmentary detail on the line A A in Fig.

Similar reference characters throughout the drawings indicate corresponding elements or features of construction referred to herein. l

In the drawings the numeral 1 indicates the earth or ground in which an excavation 2 has been begun, and at opposite sides of which stringers 3 and 4 rest on the surface of the ground and support track-rails 5 and G. A suitable engine-car 7 is provided and has carrying wheels S, 8, 9, 9, that are mounted on the rails. A suitable hoisting engine 10 is mounted on the car and may be either non-reversible or reversible, the latter type being illustrated and having a reversing lever 11, the engine including two winding-drums 12 and 13 which are desirable if the engine be non-reversible, and one of the winding-drums may be omitted if desired and the engine be reversible. The shaft 12 of the winding-drum 12 projects a suitable distance for driving another winding-drinn 141 which is mounted on the engine car in proximity to the winding-drum 12, and its shaft lil projects toward and in alinement with the shaft 12 and has a clutch member 15 thereon to be engaged by a companion clutch-member 16 suitably mounted on the shaft 12 and controlled by an operating lever 17, the winding-drum 14 preferably being considerably larger in diameter than the winding drinn 12. The winding-drums 12 and 13 are provided with suitable clutch operating levers 18 and 19 respectively as usual, and the winding-drum 14C is provided with a similar lever 20, so that the windingdrums may be locked to or unlocked from their driving shafts, as will be understood. The engine is provided with a windingspool 21 on which a cable 22 may be wound for moving the apparatus on its track the work proceeds, the cable extending about a sheave 23 mounted on an anchor or deadman 24.

When it is required to move the conveying car an unusually long distance it is preferable that an auxiliary hoisting engine 25 be mounted also on the engine car having a reversing lever 11', the engine being detachably connected to the winding-drum 14 in any suitable manner, as b v providing the crank shaft 26 of the engine with a pinion 27 and suitably supporting` a shaft 2S parallel to the crank shaft and mounting a pinion 29 movably thereon, so as to be moved into or out of engagement with the pinion 27 and a gear wheel 30 with which the windingdrum 14 is provided, the pinion 29 being operated and controlled by means of a suitable lever 31 to which is connected an operating rod 32 that is suitably connected to the pinion, whereby the pinion may be moved along the shaft 2S.

On one end of the engine-car a suitable upright frame is erected and preferably comprising two main posts 33 and 33 and intermediate posts 34 and 34 to the tops of which a beam 35 is secured. A rotatable guide 36 of suitable construction is mounted on the upright fra-ine, and farther up on the frame another rotatable guide 37 of suitable form is mounted between the two .intermediate posts, and another suitable cable-guide 38 is mounted between the posts 33 and 34, a guide roller 39 being mounted preferably on a dead-stop timber 40 adjacent to the lower portion of the upright frame.

A trestle is connected to the enginecar, so as to be moved thereby and extends from the end that has the upright frame thereon, the trestle comprising a suitable number of bents7 as 4l, including legs 42 and 42 mounted on wheels 43 and 43 which are movable on the ground track rails, and other similar bents 44, 45, on which are stringers 46 and 47 that are approximately horizontal and from which extend two inclined stringere 48 and 49 respectively that rest on the bent 44 and also on timbers 7 and 7 of the engine car between the posts 33 and 34 of the upright frame, the stringers supporting two track-rails 50 and 51. The track rails on the trestle as will be seen extend in the vertical plane that is angular to the ground track rails. Another bent 52 comprising legs 53 and 53 provided with wheels 54 and 54 constitutes a part of the ti'estle, being mounted on the ground track rails and supports the middle portions of the inclined stringere 4S and 49, the bent having less height than the other bents. A pair of horizontal tic-rails and 55 are connected to the engine car and also to the legs of the bents of the trestle. The terminal end portion of the trestle has a frame as j 5G mounted thereon which supports a guide sheave 57. An inclined guide for the excavating implement comprises preferably two beams 5S and 5S that extend from the surface of the ground to the upper portion of the upright frame to which they are suitably connected, and a floor 59 attached to the beams and extending from the lower ends up to within a suitable distance from the upper ends thereof, the floor preferably having a pair of upwardly converging guide-bars 60 and 60 thereon, and a guide roller 61 is suitably mounted at the upper end of the floor. A1 pair of hangers 62 and 62 are attached to the bent 52 and also to the beams of the inclined guide, and a guideroller 63 is suitably'supported under the beam of the bent. A pair of horizontal tiebars 64 and G4 are secured to the lower portions of the beams 58 and 5S and also to the frame of the engine-car. An inclined chute 65 is supported on a suitable frame 66 adjacent to the upright frame andbeyond and below the upper end of the guide-licor 59, the chute being arranged transversely of the apparatus, so as to receive from the excavating implement and deliver the earth above the track of the trestle at the lower end thereof.

ein excavating implement of suitable construction comprises a scoop 67 provided with a yoke GS that extends beyond the forward end of the scoop, and for the purpose of scraping or digging in order to excavate and to elevate the earth so that it may be discharged into the conveying car, a cable 69 is connected to the yoke and extends under the guide-roller 63 (when the imple-v ment is in excavating position) and thence up and over the guide-roller 61 and over the rotatable guide 36, thence to the winding-drum 12 to which it is suitably connected. The yoke GS is preferably connected to the sides of the scoop 67 by pivots 70 and the yoke includes a tail-bar 71 that extends across the rear end of the scoop and has a spring-linger 72 attached thereto that is provided with a projection 7 3 adapted to enter one of several holes 74 (Fig. 8,) that are in the rear end of the scoop, the latch being designed to normally prevent pivotal movement of the scpop in the yoke during digging o-perations and permitting the angle of the scoop to be adjusted with respect to the line of draft of the cable. i trip device of suitable construction is supported on a frame 7 G that is mounted on the inclined guide, so that when the scoop is at the upper end of the floor 59 the Enger 72 may engage the trip device to release the scoop and permit it to swing pivotally in its yoke, as illustrated in Fig. 7. In order to return the excavating implement to the trench a suitable anchor or dead-man 77 is fixedly supported in any suitable manner in the trench and has a gui'de-sheave 78 connected thereto, so that the guide-sheave may be lowered .in the trench as the digging proceeds, a cable 7 9 being connected to the tailbar 71 of the yoke and extending about the guide-sheave and thence under the guideroller 63 and upward above the inclined guide and thence over the rotatable guide 37, thence down to the winding-drum 12 to which it is suitably connected, it being understood that the cables (39 and 79 which for convenience are indicated as two cables may be one cable wound a tew times about the winding-drum, as is obvious. In case that the main engine is non-reversible and both winding-drums 12 and 13 are supplied, the two cables 69 and 79 may be wound on the two windingdrums as indicated by broken lines in Fig. 1 instead of both cables being connected to one of the windingdrums with a reversible engine.

The improved conveyingcar which is adapted to automatically discharge its load comprises two separable body parts, one part comprising an end S0, two sides 81, 82, and a sloping bottom S3 extendingtrom the lower portions ot' the ends of the sides to the upper portion oit the end SO, the part being provided with a pair oit' carrying wheels 84 and S5, thc companion part comprising an end S', two sides 81 and 82 matched to the ends oi the sides 81 and 82 and an inclined bottom S3 similar to the bottom 83, but arranged in reverse order thereto, said companion part having carrying-wheels 84 and 85, all the wheels being mounted on the rails 50 and 51. rl`he car comprises also a draft frame S6 which secured to the sides 81 and 82 and extends between guide-bars 87 and 87 secured to the sides S1 and 82, and beyond the end 80 when the two parts or sections of the car are joined together. A lock-bar 88 is con nccted by a pivot 89 to the end SO and normally rests by gravity in notches 90 and 90 in the draft frame when the two parts of the car are together in normal position after contact with the dead stop 40, the lock-bar SS'being unbalanced on its pivot and extending beyond one side of the car. lVh en the lockbar is moved out of the notches the part of the car on which it is mounted may move away from the other part within the draft frame. A cable 91 is connected to thc end Y S0 of the conveying car and extends about the guide-shcave 57 and thence over the rotatable guide 38 to the winding-drum 111 to which it is connected, for moving the car outward on the trcstle with its load, and another cable 92 is connected to the draft. frame SG and extends over the gl1idc1'ollcr 39 to the opposite side of the wimling-drum 11i to which it is connected, it being understood that the two cables 91 and 92 may consist of a single cable wound a iew times about the winding-drum to prevent slippage. In order to dump the load from the conveying car a post 93 is supported on the trestle land has a guide-bar 94 thereon adapted to be engaged by the projecting end of the lock-bar 88 to tilt it from the notches in the draft frame and thus permit the cable 91 to draw one part of the car away from the companion part, and thus permit the load to fall out between the two separated parts.

In practical use the main engine will operate the excavating implement and draw it up and down the inclined guide, and the winding-drum 14e being connected with the winding-drum 1Q will be operated also by the main engine to automatically move and control the conveying car, the auxiliary engine being disconnected from the other apparatus, but in case it be desired to move the earth an unusual distance out on the trestle the winding-drum 14 may be disconnected from the main-engine by means ot' the lever 17 and the auxiliary engine may be connected to the winding-drum 14 by .means of the lever 31, so that the conveying car may be operated and controlled independently by the auxiliary engine which, however, may be operated by the attendant who operates the main engine. lVhcn the exea ating implement is filled and -drawn to the upper end of the inclined guide, so that it may be tilted over the guide roller G1 to discharge the earth into the chute (S5, the conveying car will stand below the lower end of the chute against the dead stop to receive the load and will be moved outward on the trestle, while the excavating implement descends into the trench, and as will be apparent the excavating implement and the conveying car may be moved simultaneously in harmony by means of thc main engine alone.
